| 摘 要： | 从磁性粒子的静磁场出发，分析计算了由软，硬磁性两相粒子随机混合的双相磁体中的静磁作用，计算得出：取向的硬磁粒子施加于磁体中软磁相上的静磁场，在磁化方向上的分量为１个正值，它正比于硬磁相的体积分数及其饱和磁化强度，其作用将提高软磁相的矫顽力。

| Abstract: | The dipolar interaction in a mixed two - phase magnet of soft and hard magnetic particles was analysed. It was deduced that the aligned hard magnetic particles exert a positive average magnetic field on the soft magnetic particles, which enhances the coercive force of the soft magnetic phase. This average field along the magnetization direc- tion of the hard magnetic phase is proportional to the volume fraction of the hard phase in the magnet and its saturation magnetization. |
